Description   Landslide 18.6 is now available for download on the Spirent customer support website. As NEMs and Carriers continue their fast track towards deploying the first commercial 5G SA network, one of the critical barriers to overcome will be the correct interconnection with legacy networks to guarantee mobility, services’ coverage and offloading. To aid this tremendous effort, release 18.6 continues Landslide’s strategic feature set alignment by (1) upgrading NAS to 3GPP Rel.15 June, 2019 and NGAP to Rel.15 July 2019 specifications versions in all related test cases and (2) enhancing mobility testing support with Intra-5G N14 handovers, 5G VoNR to VoWifi handovers, 4G to 5G inter-technology handovers with the initial attach on 4G and security continuity after handover.  Furthermore, the Service Based Architecture library of testcases is enhanced in Landslide 18.6 with the new NEF testing application and NEF emulator (exposing N51 and N29 interfaces). Other key areas of mobile network testing have also been enhanced: for instance, the Emergency Services testing offering in Landslide 18.6 adds support for PSAP testing along with the new PSAP emulator, which can be upgraded to support NG911 requirements. Get all the details - Landslide 18.6 Release True 5G Test Cases R18.6 is the tenth Landslide release with True 5G (SA) Core test cases. New use cases include:  4G to 5G inter-technology handovers with the initial attach on 4G or on 5G NSA 5G VoNR to VoWifi (5G ePDG) handovers UE Info support for IPSec keys when using the NWu interface.
